Questions

Why is the bounce rate for a few particular campaigns on Facebook always one?

I am trying to run a few campaigns through social media and while I am getting good replies in terms of comments and messages, I am not sure why my bounce rate is always 1 with a session time of 0. I even tried going through the links that I am using to track on my side and even navigated through few pages and it still shows 1. I have already checked google analysis code and it is applied on all pages. I am really clueless at the moment.
